Patented Aug. 5, 1919.

' Application filed July 17, 1918. Serial in. 245,429.

To all whom it may concern:

Be it known that I, HENRI FORD, a citizen of the United States ofAmerica, residing at Dearborn, in the county of Wayne and State 5 ofMichigan, have invented certain new and useful Improvements in Engineand Radiator Assemblies, o-f-which the following is a specification,reference being had therein to the accompanying drawings.

The tractor which I am now extensively placing on the market includes anovel engine and radiator assembly, and particularly a cylinder frontcover which affords a well for a fan pulley, a' bearing for a sta rlterhe radiator is mounted between the cylinder front cover and a top tankwhich is braced relative to the cylinder block by a tank connection, andsaid connection supports a fan bracket and together with the top tankassists in supporting the main fuel tank of the tractor.

The assembly asoutlined above permits of that part of the tractor beingexpeditiously and economically manufactured,

and" the construction entering into the' assembly will be hereinafterconsidered and then claimed.

Reference will now be had tothe drawing,

so wherein Figure 1 is a side elevation of the engine and radiatorassembly, partly broken away and partly in section;

Fig. 2 is a perspective View, on'a' small scale, of .the cylinder frontcover; Fig. 3 is a longitudinal sectional view of the same, and

is a rear elevation of the cylinder front cover and radiator, showingthe fuel .tank in cross section.

- In the drawings, the reference numeral 1 denotes a cylinder blockwhich-z'nter altohas cylinders 2, a water jacket 3, a front flange 4:,and bottom flanges 5, said bottom flanges being connected to the flanges6 of'a crank case 7. The flanges 6, at the forward end of the crank case7, protrude pastthe front flange 4 of the cylinder block, and connectedto the forward end of the crank case and'resting thereon is a horizontalwall or ledge 8 of a cylinder front cover 9, said cover having a flange10 connected, to the flange 4 of the cylinder block. The cover 9 has anH opening and connection 11 for a commutator 12, and the horizontal wallor ledge 8 of said cover is at the rear marginal edge of a well 13providing clearance for a belt pulley 14 which is mounted on the forwardend of the engine crank shaft (not shown The -well 13 has a rear wall 15and a curved front wall 16, with a flan e or side wall 17 at one side ofthe well an a bottom radiator connection 18 at the other side of saidwell.

The bottom radiator connection 18 is somewhat in the form of an elbowformed integral with the cylinder front cover, said connection havingthe rear end thereof terminating at the flange 10 of said cover so as tocommunicate with an angularly disposed jacket connection 19 forming partof the cylinder block 1. The connection 18 has a drain cup 20 and theforward end thereof terminates at a lateral flange 21 forming the frontmarginal edge of the well 13.

The curved wall 16 of the well 13, below pending application filed April15, 1918,,

Serial N o. 228,590;

Suitably connected to the flange 21, as at 27, is a bottom radiator tank28 having a connection or apertured boss 29 to register with theradiator connection 18 of the cylinder front cover.

Connected to the bottom radiator tank 28 is a radiator comprising a core30,- side members 31, and an'overflow pipe 32,. said overflow pipeextending through the bottom of the tank 28. Theradiator core 30 is of aconventional form and the side members have openings 33 so that'air maycirculate through the sides of the radiator. The side members 31 havethe rear edges thereof shaped, as best shown in Fig. v3, to provide aninclosure for a rotary fan 34,which assists in cooling water in theradiator, by sucking air through the fins and around the tubes formingthe core of the radiator. The radiator core is constructed asa unit andattached to the upper end thereof is a top radiator tank 35 having acover 36 and a extension 38 and said tank and its extension 7 have aflat bottom wall and a convex unner wall, said walls imparting afinished effect to the top of the radiator. I

Thefiat bottom wall of the tank extension 38 has an opening 39communicating-with a top tank connection 40, whichis Suitably se-'thereof. a I a 7 At the juncture of the tank :35and its extension 38there is a' centralvdeflector 51 for the water or cooling agent, so thatthe water will be distributed toward the sides L ofthe tank andradiation;

The rear end of the tank extension 38 provides a hood 4:2 for theforward end of a fuel tank 43, said tank being oval in cross section, asbest shown in Flg. 4, and sus-.

pended in the hood by a strap 4A having its ends held by the hood,'as at45, A suitable packing 46, as felt,'is interposed'between the front ofthe fuel tank 43and the hood 442.. t

The top tank connection lOhas a depending bracket or bearing 47supportin a shaft 48 for the fan 34, said fan shaft aving'a. pulley 4:9for a belt 50 that extends into the well 13 and is trained under thepulley 14 therein. v

From the foregoing it will be observed that the construction affords athermosyphon cooling system and the circulation of the water or coolingagent has been indicated in Fig. 1 by arrows. The system acts on theprinciple that hot water seeks a higher level than cold water;consequently,

- when the water reaches a certain heat,

approximately 180 Fahrenheit, circulation commences and water flows fromthe bottom of the radiator tank '28 through the connections 18 and 19,up through the Water jacket 3, through the connection 4:0 into the topradiator tank 35, and down through the radiator coreto the lowerradiator tank 28,

to repeat the process. Considerable importanceQis attached to the factthat the cooling vsystem is maintained through a few rigid connections,in contradistinction to hose or flexible connections, and that the rigidcon nections l constitute supporting members which permit of the engineand the radiator assemblyas above described. The assembly is such as tobe compact and "permit of this .part of the tractor being expeditiouslyassembled' with full assurance that the ele ments entering into theconstruction will stand the vibrations and rough usage to which the sameare subjected during operations of the tractor particularly on rough andirregular soil.

The engine and radiator assembly also lends a distinct appearance to theforward end of my tractor whereby it may be read ily distinguished fromother makes of tractor, and this is especially noticeable about the topradiator tank, since said tank, its extension and the fuel tank are allin alinement and have the appearance of a single structure formin a roofor canopy over the power plant of t e tractor.

cured to the tank extension 38 and to a cylin der head all mounted onthe. cylinder block 1 and communicating with, thegjacket 3" What I claimis 1; In an engine and radiator assembly, a

cover adapted to establish communication between said tank and saidengine, a top tank on said radiator having a rear extension, a rigidconnection between said engine and the rear extension of said tank, arotary fan supported from said rigid connection, and power transmittingmeans extending from said fan in said front cover.

11. Inan engine and radiator assembly, an engine, a front covertherefor, a radiator on said cover, a fan in the rear of said radiator,and power transmitting means for said fan adapted to be driven fromwithin said front'cover.

.12. In-a tractor, the combination of an engine, a radlator 1n front ofsaid englne, a

top tank for said radiator, and a fuel tank above said engine as acanopy therefor and end held by said top extension supported from saidengine, and a fuel tank above said engine having its walls in alinementwith the walls of said tank and the extensionv thereof.

14. In a tractor, the combination of an engine, a radiator in front-ofsaid engine, a top tank for said radiator, having a rear extensionsupported from said engine, and communicating therewith, and a deflectorin the rear extension of said tank adapted to deflect a cooling agent tothe sides of said tank.
